A fire is listed here when it is located in Sweet Grass County. Each complex is counted once, through its parent: the parent carries the complex's acres, and its member fires are listed beneath it without being counted again. A fire that crossed a county line is listed with the acres that burned in Sweet Grass County, not its whole reported size. A fire located elsewhere that burned into Sweet Grass County is listed too, at its Sweet Grass County acres, and is not added to the Sweet Grass County fire counts. County lines come from a different boundary dataset than state lines, so Sweet Grass County's acres are counted along county lines and can differ a little at the edges from the figures on the state page.
